Do not underestimate the power of the SQLite console (aka the sqlite3 binary). I've been using php with sqlite module compiled in and perl with DBD::SQLite for long time. but after I wrote a simple 55lines SQL_direct parser for the console, I prefer using it. it gives me full access to all the .commands and input/output blobs via tempfiles. I just build up a file of SQLite commands and SQL queries to be executed and just parse it through like in: $textoutput= `$sqlite $database < $sqlcommandfile`; Blobs are handled via files. -- MortenB

If you're using C, I strongly recommend checking out PDFLib from Thomas Mertz. It's a very easy to use little library that lets you generate high quality PDF files. PDF files have the advantage of being useful for printing as well as emailing. Many businesses like the cost savings of emailed invoices. If you're wanting HTML output, my own libtemplate is a good choice for generating your output (http://www.lazarusid.com/libtemplate.shtml). Plain text files are also nice for their portability, and printf or your language's built in facilities for generating formatted text are strongly to be preferred.

[sqlite] write invoices
I have created a small sqlite3-database with three tables. When I have done my qeuries I want to write invoices based upon my data. In what direction do I turn. Where can I find open source free programs for this purpose. Windows Home Edition. Jan Ekström

Bah, this is a red herring. I've built Python sites that handle millions of hits a day on top of Zope, and Zope isn't that efficient. There's sites running SkunkWeb that handle tons of load, and we're not talking about anything close to that here. Algorithms are 99% of the problem, language performance is 1%. People often blame the language (Python, Perl, Tcl, etc) for their own inability to understand algorithm behavior. O(N^2) is gonna suck on every platform, even if written in assembly when N becomes some reasonable number. Use what you're comfortable writing in, because that's what you'll be productive in. If that's C++ great, but don't not use a language because of performance concerns unless you truly have a C10K problem. Chris -- | Christopher Petrilli | [EMAIL PROTECTED]

See this month's Linux journal for my opinions on the matter of interface languages. SQLite3 is a dream to work with in a C++ CGI program, especially true if you make use of my web template library (http://www.lazarusid.com/libtemplate.shtml).

Re: [sqlite] Good Graphical Tool for 3.x
Sorry for the delay. Yes it should run on linux, at least it does on my box. Could you provide the link which setup.tcl is missing (or a screenshot from the error). I know those error windows are a little bit strange ... Or you try it from an other linux machine. May be it is a network issue.

All, could someone please tell me why this query doesn't work with 3.1.3 (with 3.0.8 it works): SELECT max(Sub.Sendung) FROM (SELECT S.Sendung FROM Auftrag AS A, Sendung AS S WHERE(A.PosyDat = 1 AND A.PosyDat = S.PosyDat) AND (A.PosyNId = 6 AND A.PosyNId = S.PosyNId) AND (A.DateiNum = 1 AND A.DateiNum = S.DateiNum) AND (A.ReprintNum = 0 AND A.ReprintNum = S.ReprintNum) AND (S.Sendung >= 1 AND S.Sendung <= 600) LIMIT300) AS Sub; Thanks a lot, Michael
